AZTEC CALENDAR STONE

The four squares that surround the central deity represent the four previous suns or eras, which preceded the present era, 4 Movement (Nahuatl: Nahui Ōllin). The Aztecs changed the order of the suns and introduced a fifth sun named 4 Movement after they seized power over the central highlands.[8] Each era ended with the destruction of the world and humanity, which were then recreated in the next era.

CENTRE

In the center of the monolith is the face of the solar deity, Tonatiuh, which appears inside the glyph for "movement" (Nahuatl: Ōllin), the name of the current era. The central figure is shown holding a human heart in each of his clawed hands, and his tongue is represented by a stone sacrificial knife (Tecpatl).

4 WIND

The top left square shows 4 Wind (Nahuatl: Nahui Ehēcatl), the date on which, after 364 years, hurricane winds destroyed the earth, and humans were turned into monkeys.

4 JAGUAR

The top right square represents 4 Jaguar (Nahuatl: Nahui Ōcēlotl), the day on which the first era ended, after having lasted 676 years, due to the appearance of monsters that devoured all of humanity.

4 RAIN

The bottom left square shows 4 Rain (Nahuatl: Nahui Quiyahuitl). This era lasted 312 years, before being destroyed by a rain of fire, which transformed humanity into turkeys.

4 WATER

The bottom right square represents 4 Water (Nahuatl: Nahui Atl), an era that lasted 676 years and ended when the world was flooded and all the humans were turned into fish.
